MITIGATION STRATEGIES
  1. 1

    Invest in domestic diamond cutting and polishing to capture value-added margins

  2. 2

    Strengthen Canadian diamond brand identity for conflict-free and ESG positioning

  3. 3

    Advance exploration of Star-Orion South and other potential Canadian deposits

  4. 4

    Develop strategic positioning against lab-grown diamonds through provenance marketing

  5. 5

    Explore industrial diamond applications in advanced manufacturing and drilling

CUSMA IMPACT

Rough diamonds trade essentially tariff-free globally, and CUSMA provides no material barrier to Canadian diamond exports. The Kimberley Process certification supersedes trade agreement provisions for diamond trade governance. Canadian diamonds command premiums for conflict-free certification and provenance traceability, independent of trade agreement frameworks.

SUPPLY CHAIN RISK

All three major Canadian diamond mines (Diavik, Ekati, Gahcho Kue) are in the Northwest Territories, creating extreme geographic concentration. Mine life limitations mean Canadian diamond production is declining as deposits approach exhaustion. Northern logistics challenges, including ice road dependency for resupply, add seasonal operational constraints.

COMPETITIVE LANDSCAPE

Canada is the world's third-largest diamond producer by value, behind Botswana and Russia. Canadian diamonds differentiate on ethical sourcing, conflict-free certification, and Northern provenance branding. Lab-grown diamonds represent an emerging competitive threat in the engagement and fashion segments but have limited impact on industrial diamond markets.

OUTLOOK

Canadian diamond production faces near-term decline as existing mines approach end-of-life. New discovery and development is essential to maintain Canada's position in global diamond markets. Trade policy exposure is minimal; the primary risks are geological and competitive (lab-grown substitution).
